An apparatus and method for protecting a gas container interior, where an inlet and exhaust manifold include a port assembly attachable to a port of the gas container is provided, the gas container interior is exposed to sequential self-saturating surface reactions by sequential inlet of reactive gases via the port assembly and the port into the gas container interior, and reaction residue is pumped via the port and the port assembly out from the gas container.

An apparatus of coating a filter substrate comprising a plurality of channels and an apparatus is disclosed. The apparatus comprises: (i) a containment means for receiving a pre-determined amount of the liquid; and (ii) a liquid dosing head arranged to dispense the pre-determined amount of the liquid into the containment means over an upper end of the filter substrate. The containment means is locatable at an upper end of the filter substrate; and the liquid dosing head comprises a plurality of apertures for dispensing the liquid onto the upper end of the filter substrate.

A coated pipe to transmit produced fluids in a system configured to recover hydrocarbons from a subterranean formation may include a pipe component configured to transmit the produced fluids and having an internal surface defining an inner diameter of the pipe component; and a coating deposited on the internal surface of the pipe component and configured to extend the life of the pipe component by mitigating erosion caused by the produced fluids during transmission thereof.

A coating composition is provided that is useful in coating metal substrates such as interior and/or exterior surfaces of food or beverage cans. In preferred embodiments, the coating composition is formulated using a physical blend of a preformed resin system and an alkali-soluble resin additive.

A coating method includes a first step for spraying, onto an inner area of an opening part of a cylindrical body having a bottom and arranged horizontally, a first coating material of synthetic resin containing non-volatile components while rotating the cylindrical body around a central axis thereof. After the first step, a second step is performed for spraying, onto an inner area of a barrel part of the cylindrical body, a second coating material of synthetic resin containing a lower proportion of non-volatile components than that of the first coating material while continuing to rotate the cylindrical body. After the second step is performed and before the volatile components of the second coating material vaporizes, a third step is performed in which the rotation of the cylindrical body is stopped, the cylindrical body is placed vertically, and the volatile components of the second coating material are vaporized.

A substrate coating apparatus is disclosed. A substrate coating apparatus comprises: a source of a washcoat; a washcoat showerhead for discharging the washcoat towards an upper surface of a substrate; a conduit fluidly connecting the source of the washcoat to the washcoat showerhead for supplying washcoat to the washcoat showerhead; a headset for engaging the substrate to locate the upper surface of the substrate below the washcoat showerhead; and a vacuum generator for drawing the washcoat discharged from the washcoat showerhead through the substrate. The headset comprises a headset seal for engaging against the substrate. The headset seal comprises a perimetral portion that extends around the headset and a cantilevered portion that extends down from the perimetral portion and which is configured to engage against a sidewall of the substrate.
